OTTO VINCE VANICEK, OF TEMPLE, TEXAS.

VALVE-SPRING COMPRESSOR AND LIFTER.

Application filed July 5, 1922. Serial No. 572,837.

To all 'whom t may cmwern:

' Be it known that O'r'ro VINCE VANICEK, a citizen of the United Statesof America, residing at Temple, in the county ofl Bell and State ofTexas, have invented certain new and useful Improvements in ValveSpringCompressors and Lifters, of which the following is a specification.

This invention relates to certain new and useful improvements in valvespring compressors and lifters, and has particular reference to aportable device or hand tool, adapted for compressing the spring upon avalve stem to permit the easyremoval of the retaining nut for the springthat is threaded upon the lower end of the valve stem.

The primary object of the invention resides in the provision of a valvelifter and spring compressor'wherein the rod engaging the valve at thehead of the stern is ad justable in length to accommodate the tool foruse in connection with valves of various sizes.

Vith the above general objects in view `of the invention is betterunderstood, the

same consists of the novel form, combination and arrangement of partshereinafter more fully described` shown in the accompanying drawing andclaimed.

In the drawing, wherein like reference characters designatecorresponding parts throughout the several views, l

Figure 1 is a side elevational view of a valve spring compressor andvalve lifter constructed in accordance with the present invention,

Figure 2 is a vertical sectional view taken on line Il-II of Fig. 1showing the longitudinally adjustable and extensible valve engaging rod,

Figure 3 is a detail sectional view taken on line III-III of Fig. 2showing the pivotal strap connection between the tensioned slidingcollarupon the valve engaging rod and the curved lever arm that engages thelower end of the valve spring,

Figure 4 is a detail sectional view taken on line IV-IV of Fig. 2showing one section of the valve engaging rod threading into the othersection thereof, and

Figure 5 is a fragmentary plan view of the lower end of the curved leverengaging the valve spring, showing the bifurcated end thereof forstraddling the valve stem.

The present device being designed for compressing the spring upon avalve stem to permit the easy removal of the retaining nut threaded onthe valve stem for said spring, the same embodies a valve engaging rodincluding an upper section 1 having a head 2 at the upper' end thereof,while the lower end thereof is threaded as at 3 to be adjustablyreceived in the internally threaded tubular member l having a lniurledflange 5 at the upper end thereof to facilitate rotation of the tubularmember, a tapering valve engaging` head 6 being carried b v the lowerend of the tubular member and formed integral therewith as clearly shownin Figs. 1 and 2. The tubular member l being adjustable upon the rodsection 1, the same is maintained in a set position by the jam nut 7threaded on the portion 3 of the rod for engagement with the upper endof the tubular member as clearlr7 illustrated.

A lever arm 8 is pivotallv associated with the valve engaging rod andhas a lower arched end 9 terminating in a bifurcated end l0 as shown inFig. 5 for straddling the lower end of a valve stem to engage the lowerend ot the spring upon a valve stein, The upper end 11 of the lever arm5% is pivotally connected as at 12 to the curved end 13 of the operatinghandle 11h the lower face 18L of the curved end of the handle beingconvened and engaging the head 2 upon the upper end of the valve rodengaging section 1.

The pivotal connection between the lever arm 8 and the valve engagingrod imzludcs a sleeve or collar 15 freely slidalilc upon the rod sectionl. the collar 15 carijving (flianlctricallv opposite pivot pins 1G thatengage the opposite sides of the looped strap bearing 17 of the leverarm 8, as clear-lv shown in Figs. 1 to 3. coil spring 1S surrounds therod section 1 between the head 2 thereof and the upper end of the collar15 for normallT holding the valve engaging rod in its shifted position.To prevent rotary movenient of the valve engaging rod relative to thelever arm 8, an arm carried by the head 2 ofthe rod section 1 isbifnrcated as at 19 for enclosing the upper end 11 of the lever arm 8.

From the above detail description of the CFI device, it is believed thatthe construction and operation thereof will at once be apparent, itbeing noted that the valve engaging rod is adjustable in length toaccommodate the use thereof in connection with valves of differentsizes, the head G upon the tubular member el of the valve engaging rodbeing placed in engagement with the valve, while the lower bifurcatedend l() of the lever arm 8 straddles the lower end of the valve steinand engages the lower` end of the spring surrounding the same. Bydepressing the handle lever 14, the valve engaging rod is loweredagainst the tension of the spring 18 while the collar 15 also movesupwardly upon the rod section 1, thereby compressing the valve springand permitting the easy removal of the retaining nuts therefor. TWhenthe valve spring has been placed under full compression, the lower sidewall 13b of the lower arched portion of the curved end 13 of the handlelever 14 is presented for engagement with the head 2 upon the rodsection 1, and in this position the handle lever 14 is retained againstaccidental movement during the operation of removing' the retainingmeans for the valve spring. In a similar manner, the valve spring may beplaced upon the valve stem and the retaining nut therefor properlyapplied.

While there is herein shown and described the preferred embodiment ofthe present invention, it is nevertheless to be understood that minorchanges may be made in the invention without departing from the Spiritand scope thereof as claimed.

lhat is claimed as new is z 1. In a valve spring compressor7 a valveengaging rod formed of extensible sections with the lower end thereofadapted for engagement with a valve, a curved lever arm slidably andpivotally associated with the valve engaging rod with the lower endthereof adapted for engagement with the lower end of a valve spring, andahandle lever pivotally connected to the upper end of the curved leverarm and in engagement with the upper end of the valve engaging rod.

2. In a valve spring compressor, a valve engaging rod formed ofextensible sect-ions with the lower end thereof adapted for engagementwith a valve7 a curved lever arm slidably and pivotally associated withthe valve engaging rod with the lower end thereof adapted for engagementwith the lower end of a valve spring', a handle lever pivotallyconnected to the upper end of the curved lever arm and in engagementwith the upper end of the valve engaging rod, the sliding and pivotalconnection between the lever arm and the valve engaging rod including acollar slidably mounted upon said rod7 and a strap portion carried bythe lever arm pivoted to said collar.

3. In a valve spring compressor, a valve engaging rod formed ofextensible sections with the lower end thereof adapted for engagementwith a valve, a curved lever arm slidably and pivotally associated withtheV valve engaging rod with the lower end thereof adapted for.engagement with the lower end of a valve spring, a handle leverpivotally connected to the upper end of thel curved lever arm and inengagement with the upper end of the valve engaging rod, the sliding andpivotal connection between the lever arm and the valve engaging rodincluding a collar slidably mounted upon said rod. a strap portioncarried by the lever arm pivoted to said collar, and cooperating meanscarried by the valve engaging rod and the upper end of the lever arm vtoprevent rotary movement of the rod relative to said arm.

4. In a valve spring compressor, a valve engaging rod formed ofextensible sections with the lower end thereof adapted for engagementwith a valve, a curved lever arm slidably and pivotally associated withthe valve engaging rod with the lower end thereof adapted for engagementwith the lower end of a valve spring, a handle lever pivotally connectedto the upper end of the curved lever arm and in engagement with theupper end of the valve engaging rod, the sliding and pivotal connectionbetween the lever arm and the valve engaging rod including a collarslidably mounted upon said rod, a strap portion carried by the lever armpivoted to said collar, and a bifurcated member carried by the upper endof the valve engagii'ig rod straddling the upper end of the lever arm'to prevent rotary movement of the rod relative to said arm.

In testimony whereof l aHix my signature.
